Climate Facts: Greenhouse gas concentrations at highest levels in 2 million years, says UN

The complexities of climate change and its associated jargon can be difficult to understand.

TheCable’s quick climate facts will help demystify these concepts through easy-to-understand and straightforward explanations.

Here are some to keep at the tip of your fingers:


  • The United Nations says to keep temperatures from exceeding 1.5°C, emissions must drop to 7.6 percent every year from 2020 to 2030, and 2.7 percent per year to stay below 2°C.
  • The world will need to decrease fossil fuel production by roughly six percent per year between 2020 and 2030 to follow a 1.5°C consistent pathway, the organisation said.
  • On the current path of carbon dioxide emissions, temperature could increase by as much as 4.4°C by the end of the century, according to the UN.
  • The UN added that greenhouse gas concentrations are already at their highest levels in 2 million years and have continued to rise.
  • In 2019, greenhouse gas concentrations reached new highs as carbon dioxide levels were 148 percent of pre-industrial levels.
